Oglethorpe, promoted to the rank of General, left Georgia in 1743, never to return. The colony cannot be called an entire success; the very philanthropy upon which it was founded deprived it to a certain extent of those enduring qualities which had made the New England colonies strong and healthy provinces. But though Oglethorpe had not accomplished all that he had wanted to do, a modern writer has paid him a high tribute when he says that he "had attained a far larger measure of success than most men could have won with such material."[202] That the colony was prospering is shown by Edmund Burke in 1759, when he said, "At present Georgia is beginning to emerge, though slowly, out of the difficulties that attended its first establishment: It is still but indifferently peopled, though it is now twenty-six years since its first settlement. Not one of our colonies was of so slow a growth, though none had so much of the attention of the Government, or of the people in general, or raised so great expectations in the beginning. They export some corn and lumber to the West Indies; they raise some rice, and of late are going with success into indigo. It is not to be doubted but in time, when their internal divisions are a little better composed, the remaining errors in the government corrected, and the people begin to multiply, that they will become a useful province."[203] Some of the "errors in the government" had come up for discussion as early as 1751, when for the first time a representative assembly was called, but it was only granted deliberative functions. The whole character of the government of Georgia was radically altered when, according to the original agreement, the colony passed into the hands of the Crown. The population now consisted of 2380 whites and 1060 negroes, and these came to be governed under a constitution of normal type consisting of a governor, council, and executive officers nominated by the Crown, and a representative assembly elected by the freeholders.
